CROSSOVER FOR TROLLEY SYSTEMS.

SPECIFICATION forming part of Letters Patent No. 607,918, dated July 26,1898.

Application filed November 21, 1896. Serial No. 612,958. N0 model-l T0ctZZ whom it may concern.-

Be it known that I, CHARLES E. DAVIS, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain Improvements in Crossovers for Trolley Systems, ofwhich the following is a specification.

My invention relates to crossovers for trolley systems, and has for itsobject to provide a new and improved crossover, of which the followingis a description,reference being had to the accompanying drawings,wherein- Figure 1 is a plan view of a crossing provided with my improvedcrossover. Fig. 2 is an enlarged view of the crossover. Fig. 3 is asection on the line 3 3, Fig. 2, with parts omitted. Fig. 4 is a view ofthe trolley-wheel and support.

Like letters refer to like partsthr0ughout the several figures.

The crossover herein described is particu-' larly adapted to be used inconnection with overrunning trolley-wheels and is used on trolley-wireswhich cross each other. WVhen said wheel is running on one of thetrolleywires, the ordinary crossover cannot be used for the reason thatthe support to which the trolley-wheel is connected will come in contactwith one of the trolley-wires and thereby obstruct the passage of thetrolley-wheel.

The device hereindescribed allows an overrunning trolley-wheel to beused Without such wheel being obstructed by the parts of'the crossover.The trolley-wire A, Fig. 2, is broken, as shown, the ends beingconnected to the rigid conducting loop or frame B, so that theelectrical connection between the two wires remains unbroken. This rigidloop or frame consists of the two arms D D, connected by the cross-pieceD, said cross-piece being in a plane above that in which thetrolley-wires are located, the ends of the trolleywires beingconnected-to the arms D in any desired manner. A bridge-piece B ispivotally connected in any desired manner to the frame B and is sopositioned that when engaged by the trolley-wheel it will be moved so asto form a continuous connection between B, the weight B being connectedwith said arm and being so positioned that the bridge is normally open.WVhen the trolley-wheel comes in contact with the bridge, it is moved tothe position shown in dotted lines in Fig. 2, thereby forming a path forthe Wheel. The trolley-wire C is also broken and is provided with asimilar frame and bridge and associated parts. The frames B aresupported by means of suitable guy-wires.

I have described these several parts in de tail; but it is of courseevident that they may be varied in form, construction, and arrangementWithout departing from the spirit of my invention, and I therefore donot Wish to be limited to the exact construction herein shown anddescribed.

The use and operation of my invention will be readily seen from theforegoing description.

Then this crossover is used, itis of course evident that the cars musttravel the same way at all times on the cross-lines.

I claim- 1. A crossover for trolley systems having overrunning trolleyscomprising a broken trolley-wire, an electrical connection between thetwo parts, of said wire, a normally open bridge-piece pivotallyconnected in proximity to one end of said broken trolley-wire, andprojecting above the same in the path of the trolley-wheel so as to bemoved to bridge the break when engaged thereby, a weight below thetrolley-wire connected with said bridgepiece so as to normally hold itopen.

2. A crossover for trolley systems co1nprising a rigid loop to which theends of the trolley-wire are adapted to be connected so as to leave aspace between them, said loop provided with engaging pieces adapted tobe con nected with supporting-Wires, a bridge-piece of the trolley-Wireand form a substantially pivoted to said loop and provided with anaccontinuous pathway for the trolley-wheel. tuatin device which normallvholds it o 361], 4
